Survey participants were asked (but not required) to provide information about their professional roles, affiliations, years of experience, and clinical areas of expertise. For professional roles and affiliations, participants were asked to select all that apply and/or write in an alternate response. Few respondents reported more than one clinical role (e.g., Genetic Counselor and Clinical Lab Director, n = 2). Those with a clinical role who also identify as non-clinical researchers (n = 21) were assigned to their clinical role for the purpose of summarizing these data. Similarly, there were few respondents who reported more than one affiliation, with the exception of Academic Institution AND Hospital or Medical Center (n = 54). Those reporting more than two professional roles or affiliations were classified as "Other."The total percentage of clinical areas of expertise adds up to >100% as we report all responses from participants with multiple areas of expertise.
